Issue with running the script: IndexError: list index out of range

Hello, I have encountered an issue while trying to design oligos for my experiment. The script threw an IndexError, as shown in the output below.
The fasta file is the same I used for aligning, the bam file also works fine for other applications but I'm not ruling out my files being the cause.
I'd be deeply grateful for any help, thanks!
